Before we progress any further with the software, we need to know what’s actually happening to the eyes. This means monitoring each eye with some pupil tracking, exposing something like a set of vectors for eye movement to Unity, so that we can measure the effect of our virtual environments on eye position. This has…
IR retinal safety
At the moment all software work is paused until we have the hardware ability to track the eyes as we desire. Part of this process is to ensure, in our specification of the eye tracking cameras, that we do not produce too much infra-red radiation (in the LEDs we use to both illuminate and help…
An interesting paper reviewing current eye trackers and the history of eye tracking
I’ll just leave the link here for future reference 😉 https://journals.sagepub.com/doi/full/10.1177/2055668318773991
Affordable EyeTracking – working towards a new camera PCB
We keep coming back to the basic fact that we need to know what the eyeballs are doing. This requires an eye tracker which does what we want (particularly, with a software API which doesn’t assume both eyes are coordinating in the usual way!) at a price we can afford. The corollary to this is…
Eleksmaker A3 Laser Cutter
So, I’m still trying to get the Eleksmaker A3 laser cutter to work as I need. So far, I’ve come to the conclusion that the original version of GRBL installed on the cheap Arduino nano board the “Mana” board comes with, is just no good. I’ve flashed it to v1.1 : brew install avrdude avrdude…
Hackademy – hacking Google Cardboard V2
Rather than implementing a new VR Headset for EyeSkills, could we push the price-point down even further, by hacking the standard Google Cardboard V2 design? That’s one of the questions we explored last weekend at Careable’s first Hackademy! The standard design has a capacitive button which touches the screen as user input when the user…
Another iteration of our “eye observation” open-hardware
Our goal is to get objective feedback about eye position and behaviour, which requires some sort of eye tracking. A decent eye-tracking headset costs anywhere between $400 and $10,000 dollars… which is just too much for the majority of the world who earn less than $10 a day. So, lets make it affordable!
